<p>Two ISO/IEC 10646 character repertories, defined by <a href="http://www.ietf.org/rfc/rfc1815.txt" class="rfc">RFC 1815</a>.</p> |
| 41 |
<p>RFC 1815 defines two profiled text encoding schemes based on |
| 42 |
ISO/IEC 10646. Because of the size of full ISO/IEC 10646 |
| 43 |
character set, full implemention of it is (or WAS at least |
| 44 |
at the days of <a href="http://www.ietf.org/rfc/rfc1815.txt" class="rfc">RFC 1815</a> published) too difficult, so a couple |
| 45 |
of profiled (restricted) ISO/IEC 10646-base coded character sets |
| 46 |
were defined (as <a href="http://www.ietf.org/rfc/rfc1815.txt" class="rfc">RFC 1815</a> did). (For details of these schemes, |
| 47 |
see <a href="http://www.ietf.org/rfc/rfc1815.txt" class="rfc">RFC 1815</a>.)</p> |
| 48 |
<p>Both encoding schemes (and most of such schemes) uses two octet |
| 49 |
BMP form (ie. UCS-2), the only realistic encoding form of those |
| 50 |
days. Today it should be obsoleted. But their repertories |
| 51 |
can be useful for interoperability purpose even today.</p> |

<p>The repertory of charset <a href="#iso_10646"><code>ISO-10646</code></a> is same as ISO/IEC 8859-1 |
| 57 |
(MIME name: <code>ISO-8859-1</code>. Aka Latin-1). In most situation |
| 58 |
you can simply write <code>[ -ÿ]</code>.</p> |

<dd> |
| 64 |
<p>The repertory of charset <a href="#iso_10646_j_1"><code>ISO-10646-J-1</code></a> is superset of |
| 65 |
BASIC JAPANESE plus FULLWIDTH ALPHANUMERICS plus HALFWIDTH KATAKANA, |
| 66 |
defined by JIS X 0221 Appendix 1.</p> |
| 67 |
</dd> |
| 68 |
<dd> |
| 69 |
<p>This repertory includes all available characters of Japanized |
| 70 |
Windoze NT 3.51. (Note that more characters are available |
| 71 |
in later versions of Windoze NT.)</p> |
| 72 |
</dd> |
| 73 |
<dd> |
| 74 |
<p>Description of <a href="http://www.ietf.org/rfc/rfc1815.txt" class="rfc">RFC 1815</a> does mention any character of U+21xx |
| 75 |
and U+24xx. It would be a bug, since ISO-10646-J-1 is defined |
| 76 |
as alternate of JIS X 0208, including those characters. |
| 77 |
This module also includes those characters.</p> |

| 80 |
<p>Since description of <a href="http://www.ietf.org/rfc/rfc1815.txt" class="rfc">RFC 1815</a> is ambitious, most of character list |
| 81 |
of <a href="#iso_10646_j_1"><code>ISO-10646-J-1</code></a> is made from the list of JIS X 0221 Appendix 1. |
| 82 |
(Note that <a href="http://www.ietf.org/rfc/rfc1815.txt" class="rfc">RFC 1815</a> is not referring JIS X 0221-1995 because of |
| 83 |
schedule of both memo/standard.)</p> |
